Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643164, here are decompositions:

31 + 8643133 = 8643164
43 + 8643121 = 8643164
73 + 8643091 = 8643164
151 + 8643013 = 8643164
307 + 8642857 = 8643164
631 + 8642533 = 8643164
883 + 8642281 = 8643164
967 + 8642197 = 8643164

Showing the first eight; more decompositions exist.
